Using data from long-standing clinical trials, researchers projected the cost of caring for people with Type 2 diabetes as they progress from diagnosis to various complications and death. Enrolling federally-insured patients in a simple but aggressive program to control the disease would cost the government $1,024 per person per year — money that largely would be recovered after 25 years through lower spending on dialysis, kidney transplants, amputations and other forms of treatment, the study found.

However, except for the youngest diabetics, the additional services would add to overall health spending, not decrease it, the study shows.

“There’s no free lunch here. Prevention will not pay for everything. But it’s not as expensive as it looks at first blush,” said Michael J. O’Grady, a senior fellow at the National Opinion Research Center at the University of Chicago, and one of four authors whose work is being published on the Web site of Health Affairs, a leading journal of health policy research…

In its own analysis of preventive care, CBO said earlier this month that the cost of making cancer screening, cholesterol management and other services broadly available is likely to far outweigh any savings ultimately generated.
